Abstract (en)
[origin: WO8802522A1] A process and device (10) for entering letters by means of a digital keyboard (13), an optical display (14) and a digital computer (20). To allow recognition of handwritten signs entered with the finger as block letters on a digital keyboard used as a writing field (13), the movements (18) described by the finger on the writing field (13) are detected by sensors linked to the keys (11) of the digital keyboard. The writing field (13) determines a standard size for the letters, which are preferably composed of standard linear elements predetermined by the rows and columns of keys. The letters are automatically processed by pattern recoginition by the computer provided with a memory.
